Does anyone have a chart of the frequency sweep of a vintage SVT's channel 1 set flat in the normal input (a VR or even an SVT-II would probably work as well, but not a CL or 2 Pro)? I'm still trying to suss out what's going on with my 69 SVT...been a long long time since I had it working. I saw a thread in Effects where DannyBuoy used fdeck's frequency analysis program to measure a VT pedal and find the settings where it's set flat. Turns out that setting is almost a dead nuts match for the second channel of the SVT. Sounds great, but doesn't have enough low end for my tastes. The bass knob isn't getting that clear but heavy low end that I like. The 1st channel has a great low end, but seems to scoop out the mids, but I can't figure out where. And fdeck's program makes my brain hurt too much to do it myself...tried it once and I could hear that horrible sound ringing in my ears for days and it nearly drove me insane. So if someone has measured it before, I would appreciate it if you could post it on here or at least discuss your findings. I'm more interested in the head itself rather than plugged into the cab. I think what I'm going to have to do is what I did in the old days...split the signal with a Y cable and run both channels. But I'd like to see what's doing first in case I can come up with a better solution that allows me to use only one channel. TIA!
